Multimodal Chart Retrieval: A Comparison of Text, Table and Image Based Approaches

NAACL 2024long

We investigate multimodal chart retrieval, addressing the challenge of retrieving image-based charts using textual queries. We compare four approaches: (a) OCR with text retrieval, (b) chart derendering (DePlot) followed by table retrieval, (c) a direct image understanding model (PaLI-3), and (d) a…

DePlot: One-shot visual language reasoning by plot-to-table translation

ACL 2023findings

Visual language such as charts and plots is ubiquitous in the human world. Comprehending plots and charts requires strong reasoning skills. Prior state-of-the-art (SOTA) models require at least tens of thousands of training examples and their reasoning capabilities are still much limited, especially…

MatCha: Enhancing Visual Language Pretraining with Math Reasoning and Chart Derendering

ACL 2023long

Visual language data such as plots, charts, and infographics are ubiquitous in the human world. However, state-of-the-art vision-language models do not perform well on these data. We propose MatCha (Math reasoning and Chart derendering pretraining) to enhance visual language models’ capabilities in…

mmT5: Modular Multilingual Pre-Training Solves Source Language Hallucinations

EMNLP 2023long findings

Multilingual sequence-to-sequence models perform poorly with increased language coverage and fail to consistently generate text in the correct target language in few-shot settings. To address these challenges, we propose mmT5, a modular multilingual sequence-to-sequence model. mmT5 utilizes language…

Table-To-Text generation and pre-training with TabT5

EMNLP 2022finding

Encoder-only transformer models have been successfully applied to different table understanding tasks, as in TAPAS. A major limitation of these architectures is that they are constrained to classification-like tasks such as cell selection or entailment detection. We present TabT5, an encoder-decoder…

Structured Context and High-Coverage Grammar for Conversational Question Answering over Knowledge Graphs

EMNLP 2021main

We tackle the problem of weakly-supervised conversational Question Answering over large Knowledge Graphs using a neural semantic parsing approach. We introduce a new Logical Form (LF) grammar that can model a wide range of queries on the graph while remaining sufficiently simple to generate supervis…
